摘　　要：结合薄膜聚光器的光学特性,同时考虑空间太阳形状模型、薄膜表面反射误差的概率模型,采用蒙特卡罗光线追迹法计算空间薄膜抛物面聚光系统接收面上辐射能流密度,分析薄膜聚光器的表面反射误差、焦径比、接收器的遮挡作用和接收器的位置对系统接收面上辐射能流密度分布的影响,为空间薄膜聚光系统的参数设计和性能分析提供参考。Taking into account the model of solar shape in space and membrane reflective error probability model, the flux radiation distributions of space membrane parabolic concentrator at the received plane were calculated by Monte-Carlo ray-tracing method coupling with optical properties of membrane concentrator. The influences of reflective error of membrane concentrator, focal length to diameter ratio, the shadow of receivers, the receiver locations on radiation flux density distributions were analyzed, and the simulation results present a reference for parameter design and performance analysis of space membrane concentrator.
